Multiple Font Sizes in title: (Mixture of latex and English commands)

I have an image with a title.

I wish to use a mixture of English and symbols.

The English looks fine, however the symbols come out looking too small for the reader to easily view. They look better at 'FontSize' 18.

However, I dont wish to have the English at Font Size 18 as this doesnt look good.

can title/ axis support multiple font size? if so how? thanks

figure; title('\bf My Output, \Theta');

plot(rand(10,1));
title(['\fontsize{20} Look Big' char(10) ...
    '\fontsize{10} Look small' char(10) ...
    '\fontsize{20} Mixed_{\fontsize{8} underscore}'],'interpreter','tex');

Is there an equivalent of this using the Latex interpreter?
