Luther

Luther is an orange puffball with a jester hat who has a internal power where he can switch to six different modes, each of them benefit him in one way. He has many friends, and hangs out with a lot of people since they respect him.

Personally, Luther thinks his name is really stupid so he shortens it to Luth to sound cooler.

Luther is a very naive person, but it's normally when he feels confident. Normally he's a pretty good sport towards other people and he is very curious about knowing about what they do and what they like, etc.
He only fights when he feels like he needs to, or if someone ate his food. That's kind of reasonable. 

Luther's Modes are in order:

Weight: Changes Luther's weight so he can jump extremely high or weigh a ton to surprise enemies or resist fall damage 

Velocity: Makes Luther move really fast but has to rely more on combos to get the job done 

Strength: Makes Luther stronger but his reaction times are worse and most of his attacks are predictable 

Mind: Lets Luther use telepathy and psychic powers but he's not that good at it so sometimes he messes up, he rarely uses this mode because of that but it's VERY powerful

Matter: This makes Luther take any part of the environment and turn it into any weapon, it's very usfeul when he's stuck in a pinch. He can also use this ability to gain other powers when making contact

with them, but it's really risky when its an element he's not familiar with. 

Mimic: This mode lets Luther copy his opponents powers. It's easy for him if their power is already inside them though if the enemy has a weapon he'll need to take that weapon from them (or make contact with it) and make a inferior (or superior depending on the odds) clone of it.
