This is for all who regularly participate in the Champions Battle Poll, I thought I'd make some bios stating the character's powers/abilities so that we can all have a decent knowledge of what these characters can do. I also made a strength scale to gauge the character's strength level as well as a skill scale. Here are the scales...
Strength Scale:
Level 10-planetary level
Level 9-well over 100 tons
Level 8-90 to 100 ton level
Level 7-40 to 80 ton level
Level 6-10 to30 ton level
Level 5- 1 to 5 ton level
Level 4-Enhanced human
Level 3-Peak human
Level 2-Above average human
Level 1-average human
Skill Scale:
Level 9-best on the planet.
Level 8-one of the world's best fighters
Level 7-top notch fighter
Level 6-highly skilled fighter
Level 5-good fighter
Level 4-has a few skills
Level 3-has had just a little training
Level 2-no training at all, but can throw a few punches.
Level 1-fights like a little girl.
So, now today I'm going to give you the X-Men profile, showing all of the main X-Men and some of their villains' powers/abilities. Next, I'm going to do the Justice League, Avengers, Marvel Street Levelers, DC street levleers, etc. and so on. So here are the official X-Men bios for the Champions Battle Poll, you can use this as a reference if you need a bit of info on the characters.
