Red Venom
DO NOT USE THIS GUY UNLESS YOU CAN AVOID TAKING HITS WITH VENOM. This guy has the lowest defense in the game. One supper with the buttons rammed can kill him. You don't even have to try hard with the ramming. The only advantage to him would be the fact that he is the fastest character in the game surpassing even Wolverine's Berserker Charge,or at least equaling it.
Special Attacks
Lunge Bite - QCF+P (Hit P rapidly for more hits.)
Diving Attack - (in air) QCF+P
Web Throw - HCB+P (WP = Straight ahead. MP = 45 degrees up-forward. FP = Straight up.)
Symbiote Bite - QCF+K (Hit K rapidly for the attack to continue.)
Super Attacks
Venom Web - QCF+2P
Death Bite - QCF+2K
Combos
D+WK, D+MK, QCF+2K
This is a basic super requiring combo. Do two ducking kicks into a Death Bite. Does nice damage if you are in the corner. (Not something that you want all of the time with Red Venom.)
D+WK, D+MK, FP, U+WP, WK, MP, MK, FK, QCF+P
This is a slightly complex air combo which is fun to do. Start off with two hits into a launcher. From here, follow up with fours hits and then a FK. After the FK hits, (once only), use a Diving Attack to hit them once more. You will meet the ground before them, so you can set up something else while you're at it. This can't be turned into an infinite though since they do have lots of time that they can block while coming down.
