Help to remember game on Sega 8 and 16 bit

1 game game the side view, but you can go left or right , kind of open world with dark landscapes and caves, keys, and of course creepy mobs
2 flying on a small spaceship (arkanoid top view), where at the beginning of each level showed a picture of the boss of the current level, and at the end when you pass the level, the same picture of the boss just mauled)
3 shooter on the similarity of dissent only only one character and quite complicated at the time. electro traps and spikes down on the ground there. It worse just remember. Single level on a black background and the forest, like the station a little higher, but it needs to get through the electric barriers, which need to be shot.

Of course the description is vague but that's all remembered from childhood. I would be grateful if anyone knows the desired game, but at least one.
