What constellation is the nemesis and savior of Aries?

The three enemies of Aries are as follows:

Aries is most afraid of facing Scorpio's fierce eyes, as if it can penetrate the heart at a glance, and does not know how to deal with Pisces' coquetry. The way to improve it should be to arm yourself ideologically, not to let feelings overflow, and it is best to take the Aquarius lifestyle as a model.

The second nemesis of Aries is Leo. They like to lead and dominate others, and they are born with the domineering and attractive momentum of generals. As long as what they believe is right, there is no reason at all. Originally, we were unreasonable, and most people would hide far away, but we met a lion: we quarreled and were yelled at by him, and we didn't know what the earth shook. He is more deadly than us when he is crazy. I showed my fist and he pulled out a fruit knife; I took out a fruit knife and he waved a kitchen knife; I pointed to a kitchen knife and he said nothing. He just let me try!

The third nemesis of Aries is Libra: Libra who is in a hurry to do everything is easily dragged down by Libra who is delayed by love. In the end, I really have to swallow the bitter fruit myself. It's so depressing
