well......in theory , yes there is
its somefing like this

but the only way i know how to get it i n BN5 is using a gameshark code
its the E-mods sel+R+L code, after u activate it go check the megaman opition in the start menu, tap right twice and ull find urself in the modifier page, select the On/Off option and a list of mods will apear.
there r lots of them, if u turn on 1 u will get the abilities listed for that mod and maybe change the aspect of megaman, u can also turn on lots of mods and pile theyr abilities (the 1s with orange letters r the bonus abilities and the 1s with purple letters r the drawbacks or bugs) but megaman will take the form of the last aspect-changing mod activated in the list, in case u go and turn on all mods, megaman will change into the bass cross style( i call "style" cuz its permanent, not like souls that u need to sacrifice chips or crosses that u can only activate in battles)
The bass cross style is awsm! the buster normal shot will become a 3-way shot going going in a sonicboom-ish way and the charge shot will turn into a hell's roller that hits 3 times!
the only drawback in the basscross style is a -2 megachips penalty, buts its still worth it
biggrin if u already have a gameshark or a VBA (you know wut i mean) heres the codes
