While this card was in Yugi's hand, its ATK was 1500, but when being in game, the damages were calculated as if it had 1700 ATK, probably because the ATK of "Dragon Piper" was combined with this card's ATK (200 + 1500 = 1700).
In episode 16, this card appears in a flashback Yugi has when he remembers Pegasus somehow knowing what card Yugi was going to play before he even played it. Yugi notes to Kaiba that he ran into the same power Kaiba saw at the tournament duel Kaiba was watching.
As with episode 2, this card is shown with 1500 ATK while in the hand but the damage was calculated as if it had 1700 ATK which probably means that this card's true ATK is 1700 in the anime.
In episode 88, this card appears in a flashback Marik Ishtar has when he remembers having his Rare Hunters test out the counterfeit versions of "The Winged Dragon of Ra". As they were counterfeits, the fake cards only caused the Rare Hunters to be killed by a bolt of lightning.
In episode 186, Yami Yugi uses this card during his Duel against the KC DuelTek 760 while the former was using Rick's Deck. He draws this card and five other Dragon-type monsters via the effect of "Heart of the Underdog". Yugi later discards this card and the five other Dragon-type Normal Monsters that he drew, so that "Spirit Ryu" would gain 1000 ATK for each Dragon discarded.
The attack of this monster is called Hell Fire in the original.
