Wow! Another boring characters without interesting and new mechanics for SRB2! As expected!
Instead of making someone a really interesting character, or at least interesting and new mechanics, the community, as usual, will make another Sonic characters. Since you love making them, WHY NOT MAKE BIG THE CAT, HUH? Even some joke character like Steve from minecraft will be more interesting than your weak Tanooki Yoshi and purple Taz the Tasmanian Devil with fire.
For example, there is a Piroli the Butterfly. He's interesting to play as because you feel like you're playing a BUTTERFLY and not a reskin of Sonic with new abilities. Someone even create the Pig from Bad Piggies with the mechanics of the structure of their car. You just reskinned old Blaze mod and Yoshi.
The future of custom characters in SRB2 is unknown, but while mods like Marine and Blaze are popular, it looks like it's going to be bad.
