A faint, whistling noise sounded in the skies, growing steadily louder all the while. A few citizens in the streets of Tokyo who were not already fleeing from Eleking noticed a strange light in the sky, shrouded by dark, whirling clouds. The light was pale blue, like the sky during a sunny day, streaking across the heavens faster than any jet. The few people on the streets below that had dealt with these kinds of things before ran even faster as the blue light streaked towards Eleking, growing larger and louder every second. The shape of the flying object could be seen from this distance. It was a large, whirling saucer, spinning at impossible speeds for it's large size. The blue light spun around the centre of the saucer, keeping the object in the air. Huge winds picked up as the flying saucer neared the ground, hovering over a small park that had once, a long time ago, been the temporary home of a feeding Super Gyaos back in the 90's. The saucer halted it's spinning abruptly as the blue flames temporarily stopped. But the silence was a temporary one.
Not a fraction of a second later, four huge jets of blue flame burst out of four sockets, stabilizing the object and sending hot steam flying in all directions. Through the steam, a crested head could be seen leaving the saucer. The creature gave a short huff as the saucer's edges bunched upwards into separate sections, jagged edges briefly showing before fitting snugly together in the form of a shell. The flames suddenly stopped as two arms and two legs burst forth from the sockets, with a small, thick tail trailing out the end. The creature dropped from the sky, it's feet slamming into the pavement. The area around it trembled at the huge weight of the monster slamming down. Through the smoke and steam, the creatures head rose magnificently, it's tusked maw opening to deliver a shrill wail... a challenge.
Gamera's two emerald eyes fixed on Eleking, narrowing at the sight of the alien. The great guardian had come to stop it's destruction, to deliver the humans from his fearful wrath. Gamera howled again as he lumbered forward, ready to fight.
(BTW, let's have their weights scaled. I do not want my Gamera flying across the city from one punch.
