Wayans is supposedly a big Joe fan which is largely why he got the part. The thing is his part isn't "Ripcord" from any incarnation (comic/TV series), it's using the name of an existing character and giving it to a role specifically written for Wayans to be the generic comic relief.
If Wayans wanted to really contribute to this movie and the writers wanted to give him a role of an actual Joe that held some substance, they should have written him in as Stalker and dropped this whole Ripcord schtick altogether.
