So a Pokemon uses mean look and my Scolipede has the item shed shell and uses baton pass.Will Scolipede be able to switch out or will he stay in?
I don't really get your question. Baton pass can escape mean look regardless.
Baton Pass switches out the user, passing all temporary stat increases and decreases on to the Pokémon that replaces it in battle. Even moves that ensure hits such as Lock-On are passed. Substitutes, volatile battle status ailments such as Confusion, Aqua Ring, Ingrain, and the effects of moves that prevent ordinary switching (e.g., Mean Look) can also be passed. - Bulbapedia
