Trick Room walls exist, and they use Relaxed. 10% more Defense, 10% less Speed. That Speed drop actually helps under Trick Room. For Crystal, Tyranitar is one of the most popular Relaxed users, alongside Slowbro and Slowking. There's no way to set natures in Crystal. You'll lock in Relaxed when catching or breeding in Ruby/Sapphire or later.
Relaxed raises Defense by 10% and lowers Speed by 10%. Slow physical walls, often used in Trick Room. 47 Pokemon competitively run this nature.

Competitive Role
Slow physical walls, often used in Trick Room.

- Walls and tanks that rarely attack
Choose Bold

How to Get
SynchronizeLead with a Relaxed Pokemon that has the Synchronize ability. Wild Pokemon will match its nature. (Gen 3+)
BreedingGive the parent with Relaxed nature an Everstone. The offspring will inherit it. (100% since Gen 5)
Nature MintUse a Relaxed Mint to change stat effects to Relaxed. The original nature name stays but stats change. (Gen 8+)
Other +Defense Natures
What does the Relaxed nature do in Pokemon?
Relaxed gives your Pokemon 10% more Defense at the cost of Speed. That tradeoff works best when the lowered stat isn't part of your moveset. Pokemon with Relaxed nature prefer Sour flavor and dislike Sweet.
What are the best Relaxed nature Pokemon?
Competitively, Tyranitar, Slowbro, Slowking, and Forretress run Relaxed most often. The +Defense boost complements their role, and the -Speed penalty barely affects their game plan.
Is Relaxed a good nature for competitive Pokemon?
For the right Pokemon, Relaxed is one of the best natures you can pick. The -Speed drop actually helps under Trick Room, where slower Pokemon move first. Just don't slap it on something that uses Speed-based moves.
How do I get a Relaxed nature Pokemon?
Breeding with an Everstone is the most reliable approach since Gen 5. The parent holding it passes its nature to every offspring. Synchronize works for wild catches. And if you already have the Pokemon, a Relaxed Mint from the Battle Tower changes the stat effects to Relaxed.
Should I use Relaxed or Bold?
Short answer: Relaxed for Trick Room wall, Bold for standard wall. There's no universal best. Check your Pokemon's base stats and common threats in the format you're playing to decide which tradeoff is better.
