THey are door moldings you may be able to bend them back and reglue or use m3 tape. Look in a junk yark for another odyssey that has them. They may cost too much at the dealer if they can order it. check out Car-Part.com--Used Auto Parts Market for the part! Good luck! (Some people just pull them off!)

oh believe me i tried to bend them, but they flex back to their bent shape. i think i would need something vastly stronger than tape (and probably something to apply constant pressure to the area while it sets)

underneath looks like some black tar-glue-foam stuff. i cant really tell. but i'm kind of afraid to try to pry it off and it might rip chunks of paint off in the process

You can get the parts from the dealer, from their accessories catalog. For example, from Bernardi they are 145$ (for the full set, not just the passenger rear like you seem to need):

Honda Body Side Moldings (Odyssey) - Bernardi Honda Parts and Accessories

As to taking them off, I would visit a parts shop and see what they have to remove moldings.

Good luck.
