Was Looker in the DP anime season?

Question

I think I breifly remember him when Ash and his friends were on a train in an episode.

Edit: Or any of the seasons, really.

Answer 1

Looker appeared in the following episodes (D/P):
-Frozen on Their Tracks!
-Gateway to Ruin!
-Unlocking the Red Chain of Events!
-The Battle Finale of Legends!

He also appears in the following B/W episodes:
-Team Plasma's Pokémon Power Plot!
-Team Plasma's Pokémon Manipulation!
-Ash and N: A Clash of Ideals!
-Team Plasma and the Awakening Ceremony!
-What Lies Beyond Truth and Ideals!
-Two unaired episodes

He was on the Ampharos Train, where he gave Team Rocket lunches, which made them start calling him the Boxed-Lunch Guy.
