Favorite multi-role champs?

What are some of your favorite champions that you take in 3+ roles?

I'd like to start ranking, and it'd be easier to completely learn the inside-and-out of one champion, while staying practiced with one or two other alternatives for special cases.

Take Pantheon for example, he makes an excellent top, jungle, mid, and even support champion. ADC for him is a bit challenging (but I've seen it done),but you can pretty much guarantee his roles in either of these lanes.What other champion do you guys feel have a similar attribute?
