Troika

Troika appeared in 2000 TV series called Power Rangers Lightspeed Rescue. Troika is a three-headed super monster that is the merged of Demonite, Falkar and Thunderon's crystal-like forms, this monster appears in the episode "The Cobra Strikes". He was an amalgamation of all three monsters' appearances, with each of their faces on one side of the monster's head (Demonites face is in the front, Thunderons face is on the left side and Falkars face is on the right side), It had Demonite's sword and lower right arm and Thunderon's spiked fist and lower left arm, Falkars feet and lower legs, a green colored chest-like area in the front with Thunderons crystal on the left, Demonites crystal on the right and Falkars crystal in top middle, and feathery details on its hide, abdomen, upper legs, most of its upper body, shoulders, upper arms and neck (a reference to the trio's exploding feathers scheme used in the episode "Ryan's Destiny").

After the initial defeat of Demonite, Falkar, and Thunderon, Diabolico collected their crystal-like forms and merged their likenesses together, creating Troika (pronounced as Troy-kuh). Troika was a powerful opponent, taking out the Lightspeed Rescue Rangers in record time, the Rangers then tried to used the V-Lancher Spectra-Blast on him, it just bounce off of him. Due to his immense abilities thanks to the combination, the Rangers were forced to retreat, while the Miss Fairweather was working on a project that can help the Rangers, Troika himself went out on a rampage through Mariner Bay. The Rangers returned during his assault and battle this fusion creature, he was still able to initially beat them into submission. The Rangers were then equipped with Battle Boosters, which enhanced their abilities. With this new power, the Red Ranger then charged at Troika, and successfully punched off Demonite's sword on Troika's right arm. Troika was surprised, and distracted long enough for the Red Ranger to give him a right jab, which countered Troika's own jab and punctured his chest. As much as he tried, Troika was no match. The Rangers then activated their Booster Beams, which blasted Troika, defeating him (although whether he was destroyed is unknown as he didn't explode like most Power Rangers monsters).

Troika was an arrogant monster that boasted about his power and thinking that he will beat the Rangers.
