Withstand the Lightning Strike! (雷撃を跳ね返せ！ Raigeki wo Hanekaese!) is the nineteenth episode of Ultraman Taiga.
Hiroyuki tries to leave EGIS because he thinks he is at fault for putting Homare in danger. Kana tries to persuade him otherwise, but a giant monster descends from a storm cloud.
At the hospital, Homare, died after getting shot, still sleeping on a coma. Meanwhile, Kirisaki transforms into Tregear to summon the thunder kaiju, turned into the last Ring.
Pirika went back to the HQ, waving to Kana, finished calling Saku. She gets a note that reads "I don't want to continue doing this dangerous job" alongside Pirika. Serpent interrogated in the streets by Hiroyuki, who went out alone wanting to find out Kirisaki location since he had landed Homare in the hospital. After roughing up the alien, who had no information to spare, Hiroyuki threw him aside and told him to get lost. As Tri-Squad fade in, they should be the ones to blame before the member left. Kana still reads a note that Pirika found Hiroyuki, walking straight to the hospital and seeing dead Homare. After leaving a hospital, Kana decides to stay at the park with Hiroyuki. They sit on benches but not a very good lie. The Thunderstroke Monster, Gorothunder, descended in a storm cloud near them. He took interest in the former and captured her in his belly button piercing prison before growing to giant size. Hiroyuki was unsure of what to do since fighting him would endanger Kana, but Taiga convinced him that they cannot save her if they do not take action. Hiroyuki transforms into Taiga to fight Gorothunder, watched again by Kirisaki.
Taiga quickly changed to Titas after getting knocked down. He used the Electro Buster, but it was overpowered by Gorothunder's beam, and he was then knocked down by Gorothunder using his club.
Kana awakened and cheered Titas on, before he fired the Astro Beam at Gorothunder to knock him away. Titas changed back to Taiga and fused into Tri-Strium. Using Taiga Tri Blade, Taiga narrowly slashes off Gorothunder's belly button prison, setting Kana free. He then uses the Titas Burning Hammer to finish off Gorothunder, who used his own beams in a futile effort to attack him. Taiga received the last Kaiju Rings that just hang on it. Hiroyuki runs to her, who woke up, and hugs tightly but members are waiting. Pirika called Hiroyuki that Homare regained his consciousness. As a punching bag starts moving, she saw Kirisaki that he holds her face to make nightmare about falling comet before hitting her using the thunderbolt. As she wakes up from her dream, she saw fishes in the aquarium.
