What is super effective against ice?

Fire, Fighting, Rock and Steel-type attacks are super effective against Ice-type Pokemon. Of all types, Ice is considered to be the worst in terms of defense. The Ice type is only resistant to attacks of its own kind and has no immunities aside from freezing and hail.

Despite its defensive shortcomings, the Ice type is valuable offensively for its effectiveness on many dual types, such as Dragon and Flying. Ice types can form strong offensive teams with Electric and Ground types. Ice types are the second rarest as of Generation VI, accounting for just under 5 percent of all Pokemon. A user with the ability Protean can change into an Ice type after using an Ice-type move.
