Appearance:
Bowser is a huge, burly, green-shelled Koopa turtle with spikes, horns, and hair. His bushy eyebrows and mane are fittingly a bright, fiery red-orange and has bright red eyes. He sports two small horns, many spikes on his shell with brown-orange spike-rings, as well as along his tail (minus the spike-rings). He wears several spiked collars around his neck and arms. He has three claws on each of his massive padded feet, four claw-tipped fingers including a thumb on each hand, and his arms are noticeably burly, indicating his vast physical strength. While his face and his shell are green, his plastron and muzzle are beige colored and his tail and limbs are an orange-tinged yellow.

Personality:
Bowser is a cruel and selfishly power-hungry king who is absolutely hellbent on taking over the Mushroom Kingdom, while occasionally wanting the entire world or even Universe, and taking their beloved Princess Peach all for himself. Upon discovering the Shattered Universe, his quest for power only strengthened as he plans to conquer that world as well, all while trying to secure his role within the Union of Despair faction he allied himself with. And yet despite his ferocious nature, he can also be seen as simply mischievous, playing with his opponents before going in seriously, and even pathetically childish in some instances, especially when something doesn't go his way. He also shows a fatherly love towards his son Bowser Jr, along with the other Koopalings that he adopted, treating them all as both his own children and minions.

Bio:
(Everybody knows Bowser and for who and what he is and does - So here's a brief backstory on how he entered the Shattered Universe)

After an unprecedented amount of crushing defeats by the heroic Mario Brothers, King Bowser Koopa decided to take a well deserved break on conquering the Mushroom Kingdom for at least a little while. While on this break, the Koopa King decides to map out various other kingdoms in which he can attempt to conquer, all while making sure his nemesis doesn't get anywhere near his points of interests and secret plans. As his minions scout out the farthest and most obscure regions of the Mushroom World, they would suddenly come across a wormhole that lead to a Universe unlike any they had seen. This world was the Shattered Universe... and once they found out the origins, and after being attacked by trigger happy pirates of said region, they hurried out to Bowser and alerted him of their discovery. Bowser immediately called for his Koopa Army, alongside the Koopalings, as they entered the Shattered dimension.

Upon reaching the new realm, they eventually had several skirmishes against what they unknowingly knew as the UUC and despite what seemed to be an unfair fight, Bowser's Koopa army managed to prevail through most of the battles and drive them back from a remote territory far in an outer rim sector. Their actions didn't go unnoticed by other factions however, as they were soon approached by the Union of Despair and were offered a place within their ranks. At first, Bowser refused the offer with haughty disdain but after a careful negotiations ending with an offer that promised power and glory, the great Koopa King eventually agreed to join them.

Skills:

• Incredible Strength/Durability: Bowser is incredibly strong, being able to lift large boulders and even heavier items if enough adrenaline rushes through his veins. He's also incredibly durable, not only in the case against blunt force, but he can also survive being plunged in boiling lava and has even fallen great distances, been blown up, crushed, as well as facing other life-threatening events, and has always been otherwise able to get back on his feet eventually. (But obviously he's not invincible)
• Leadership Moral: As King of the Koopas, his minions always look up to Bowser as their leader. His very presence establishes undying leadership towards his army as they'll do anything for him, even at times attempting to save their king if he's fallen in battle.
• Breathing Fire: Bowser's trademark ability is being able to produce continuous flares or flurries of individual fireballs at his opponents from his mouth.
• Armor: Minus his incredibly hard and durable shell, Bowser has access to a suit of armor and a hammer after partaking in a battle within the Skylanders dimension and took it as a reward. The armor provides him with additional defense and the Hammer provides itself as a weapon. The hammer can be infused with fire to issue fire-based attacks or with darkness to issue dark-based attacks.
• Dark Magic: Although its very uncommon for him to do so, Bowser is known to conjure up spells of dark magic. However, while he used to transform opponents into blocks and other items, he rather occasionally uses it to teleport from one place to another, usually if he has to escape from battle. It has even been used to reanimate his bare skeleton in one instance after being plunged into lava, transforming him into Dry Bowser. This magic is otherwise more commonly used manipulate his size and strength if need be...
• Giant Bowser (Transformation Phase 1): Through dark magic, whether supplied by himself or by his loyal servant magikoopa Kamek, Bowser can transform into a giant version of himself, usually standing multiple stories tall. His strength and durability increase in this form and is an absolute monster to fight in battle. This form is only temporary and can naturally go away within half-an-hour or so, depending on how much energy he uses in said form.
• Giga Bowser (Transformation Phase 2): A second version of his giant ability, if Bowser goes through intense and primal rage while wielding black magic, he is capable of transforming into a more animalistic giant form that is known as Giga Bowser. In this form, he's not only incredibly powerful and durable, but surprisingly fast as well, and is also known to harbor special elemental abilities in some of his attack moves, such as explosive and freezing elements. This form is only temporarily, yet diminishes twice as fast compared to his regular giant form, with only 5 minutes of maximum activity.
