河童大帝リバースライダー Kappa Taitei River Slider (Kappa Emperor River Slider)
Level 7 WATER Aqua Effect Monster
[REQUIREMENT] You can activate this by sending 1 face-up Aqua monster on your field to the GY.
[EFFECT] Choose up to 2 face-up Level 7 or lower Normal Monsters on your opponent’s field and destroy them.
*TL note: While this card’s name is likely based on the fact that the word “kappa” contains the kanji for “river”, the katakana could also be read as “Reverse Rider” or even “Rebirth Rider”. At this point, it’s unclear whether there are multiple puns involved here.

[EFFECT] Destroy all face-up monsters on your opponent’s field with 1500 or less ATK. Then, this card gains 300 ATK x [The number of monsters destroyed by this effect].
