well since we already dug into the subject of which and why didnt make it then explanation is simple, they want to put characters which had an impact and was shown a lot, radditz doesnt apply in that category plus what ever they said about attacks, nappa maybe applies but the same for him not many attacks no transform etc... I still wonder how android 18 would transform I dont understand that buddie thing they said, if they wanna add someone important they should look to add maybe tien since he has several attacks (excuse me for not being knowledgeable about the names but I saw dbz in hebew dubbing
) , yamcha might have been ok too but thats not for sure... another one could be dabura, he doesnt make that big of appearance but he has some attacks plus he looks cool rofl
other then that, dont mind about the characters, whoever wants brolly or some other movie character can download skins and ****...
anyhow I hope I explained myself...
p.s. dont call picollos transformation "taking off his cape" I really hate when u do it
