Question

What is the slowest Pokemon that can learn Avalanche?

Answer 1

Avalugg, with 28 base speed. Source.

But, you don't even need slow speed since Avalanche has a decreased priority (-4 to be exact).

Guess who's back?

Wait your back? You only said you were leaving a couple of days ago...

I got someone to tutor me.
This will help a lot. And I only left because of bad marks anyways...

Well I can't say I'm not glad you're back permanently, but when you announced you were leaving after coming back when you got your computer fixed, I sort of expected you would be gone for longer than you have what with your post on RMT, your posts on your profile and on the name change thread. Nevertheless good to see you're back!

Answer 2

Avalugg

Answer 3

The Pokémon with the lowest base speed stat that can learn Avalanche is Bergmite and Avalugg at a speed stat of 28. Just so you know though, Avalanche has a priority of -4, so it will be going last in most situations anyway.
