In Radical Dreamers: Nusumenai Hōseki, the Goblin guards in Viper Manor mention a Heckran infestation in the Kitchenette to lure Kid out of a pile of gold coins, in which she had been hiding.
Heckran possess strong magical techs. While battling the Heckran in Heckran Cave, it says, "Go ahead! Try and attack!" and refrains from attacking the party members. During this period, if the player attacks the Heckran, it counters with Water II, which deals large amounts of damage. Use this opportunity to cast Aura Whirl on the party to recover Hit Points. Heal Beam is advised if Robo is in the party. . After a brief period, a caption saying, "brief counterattack break" appears, signaling the end of this counter-attack phase of the battle. At this time, it is advised to unleash the party's most powerful techs. Using the Antipode Bomb dual-tech is ideal here. Alternate turns between attacking and healing to ensure the powerful counter does not knock-out them out.
When the player fights Lavos, it mimics that stats and techs of bosses they previously fought. One of them is Heckran.
