Every Heat Rotom card
1 printing across 1 expansion.
The short version
Heat Rotom has one printing in Pokémon TCG Pocket, in Space-Time Smackdown. It is a Basic Fire-type Pokémon with 80 HP, weak to Water, with a retreat cost of 1. The only printing is a Common. A Common has no rare-slot rate to quote — it fills the slots every pack is guaranteed to have, so opening the right expansion at all will turn one up. It comes out of the Dialga and Palkia packs. That expansion shipped in January 2025. It attacks with Heat Breath, which costs one Fire and one Colorless energy and hits for 30+. Flip a coin. If heads, this attack does 30 more damage. The card’s own words: “If the convection microwave oven is not working properly, then the Rotom inhabiting it will become lethargic.” It is drawn by Kedamahadaitai Yawarakai.
