I got a idea.
For zeed, if your lvl 2000 (Or some high lvl) you can be it, and for Omnimon, if your lvl 1337 or something, you can be Zwart. And for the real shoutmon X7 sm, if your lvl 3000, and you bought acces for it (2750 robux or something) you can use it. And, you can buy the normal alphamon for 1200 robux, and you need lvl 1000 or something. And, if you wanna be the Ouryuken, you can be lvl 1500 or something.
Its my ideas. I hope you like them.
